Multi-partite entanglement
Michael Walter, David Gross, Jens Eisert
We give an introduction to the theory of multi-partite entanglement. We begin by describing the "coordinate system" of the field: Are we dealing with pure or mixed states, with sin…
Positive Wigner functions render classical simulation of quantum computation efficient
A. Mari, J. Eisert
We show that quantum circuits where the initial state and all the following quantum operations can be represented by positive Wigner functions can be classically efficiently simula…
Recursive quantum detector tomography
L. Zhang, A. Datta, H. B. Coldenstrodt-Ronge +4
Conventional tomographic techniques are becoming increasingly infeasible for reconstructing the operators of quantum devices of growing sophistication. We describe a novel tomograp…
Quantum Tomography via Compressed Sensing: Error Bounds, Sample Complexity, and Efficient Estimators
Steven T. Flammia, David Gross, Yi-Kai Liu +1
Intuitively, if a density operator has small rank, then it should be easier to estimate from experimental data, since in this case only a few eigenvectors need to be learned. We pr…
Efficient measurement-based quantum computing with continuous-variable systems
Matthias Ohliger, Jens Eisert
We present strictly efficient schemes for scalable measurement-based quantum computing using continuous-variable systems: These schemes are based on suitable non-Gaussian resource…
Continuous-variable quantum compressed sensing
Matthias Ohliger, Vincent Nesme, David Gross +2
We significantly extend recently developed methods to faithfully reconstruct unknown quantum states that are approximately low-rank, using only a few measurement settings. Our new…
